Okay...we built our home in 2010. It's wonderful and we have all American Standard faucets, shower, toilet etc. The real complaint is that our downstairs shower valve (anti-scald) keeps "popping". Meaning the water is coming out hot and then it "pops" not allowing you to continue to turn the water to hot. It's like there is a brick wall in the handle. The first time it did it (two winters ago), we replaced the valve - no big deal and we went on with life. The next year, it "popped" again and we replaced it. Again, not a big deal thinking it's keeping us safe. However, it has now done it for a third time and third year in a row. Now we have to replace it again. It's getting expensive. The upstairs shower has the exact same head/hardware/valves and we've never had a problem. So although the anti-scald thing is great, for some reason it overdoes it's job on our downstairs shower. Yes, I still recommend it for the safety feature but this is the last time I'm replacing it. It does it again and I'll get something completely different.
